    摘要: A data delivery system is provided for delivering updated data information from a sending database system to a receiving database system. The sending database system periodically obtains, from a database updating system, a new data set having both updated data objects and unchanged data objects relative to a loaded data set stored, for example, at a receiving database system. The sending database system performs individual validity checks on the updated data objects and the unchanged data objects. A master validity check is also performed by the sending database system on the individual validity checks for the updated data objects and the unchanged data objects. The individual validity checks and the master validity check may, for example, be cyclic redundancy checks. The receiving database system, such as a flight information system associated with an aircraft, receives the individual validity checks, the master validity check and the updated data objects delivered from the sending database system.
